I To all whom it may concern.'

Be it known that l, WILLIAM H. BUSH, a citizen of the United States, residing at Framingham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Flying-Machines, of which the following is a specification.

This invention relates to an improvement in aeroplanes, of the combination type wherein permanently located buoyant bodies, as gas bags, or their equivalents, are utilized as a sustaining means, and planes provided for use in flightv as in the ordinary heavierthan-air machine. l

The buoyant bodies or gas bags, in the present machine, are arranged with a particular view to their utilization in maintaining the lateral stability of the machine in its direct elevation under the lifting propeller. and also with a view to maintaining the longitudinal stability of the machine in the independent sections grouped in direct flight of the machine under the driving propeller. n

Combination machines as heretofore constructed have proven diflicult of flight in direct lines,l owing to the air resistance of the gas bags, and the present invention aims to obviate this diiiculty in constructing and arranging the gas bags to present the minimum air resistance while yet providing suffi-- cient displacement to serve as sustalning rl`he gas bags are made up of particular relation to form a'sustainlng member of peculiar form, and are suitably sheathed to prevent rupture. 1

The propelling means involve independent elements such as lifting and driving propellers of any well-known type, and these are selectively operated from a single motor or engine at the will of the driver, so that it is possible to utilize either the lifting or driving propeller under any and all conditions of service. The respective propellers are particularly disposed with relation to the fixed gas bags in order that said gas bags may be utilized to provide, in a measure, banks of air against which the force of the propellers is more effectively directed.

The sustaining means, in the form of gas bags, are primarily designed for a displacement which will elevate a weight slightly less than that of the combined machine, driver, and contemplated passengers, and to aid in sustaining the machine in flight there is provided wings or planes of any accepted members.

type, arranged on each side of and preferbeing directly elevated or lowered, to which end the planes are mounted upon the longitudinal aXes and movable at the will of the driver, so that they 'may be arranged in either of two angularly related positions, in one being presented at right angles tothe longitudinal plane of the machine, to avoid air resistance in the direct elevation of the machine, and in the other to be arranged in such longitudinal plane of the machine for use as sustaining members in flight. The adjustment of the planes adapt their use for air brakes in direct flight, and for air-resisting elements to prevent a too-rapid descent of the machine.

The driving propeller is designed to be utilized as a rudder, in that it may be deected to one side or the other at the will of the driver, and also to be utilized asa flight retarding element through provision of means for reversing the blades. v

Tn the preferred embodiment illustrated in the drawings, the improved machine com-- e passengers as the machine is designed to carry.

Rising from the body frame are the sustaining members 2, preferably gas bags. They are of identical'construction,. and each, as more particularly shown in Figs. 1 and 3, constitute skeleton frames 3, made up of a lseries of upright bars 4, connected by cross bars 5, and constituting side frames, brace bars connecting the side frames andinaintainingthein in that spaced relation contemplated for the width of the particular gas bag. As a part of the frame thus provided, there is arranged a connecting bar 7 which extends throughout the outline of the particular gas bag and is shaped in accordance with such outline, the 'connecting bar 7 forming the edge-bar of the gas bag and the respective ends of the cross bars 5 being curved inwardly in both directions into coincidence with the bar 7. Furthermore, in

lower ,endsbeingspaced apart a distance approximating the length of the body frame, the forward portion of the connecting bar extending upwardly and inclined forwardly from such body frame, therear portion of the connecting bar also extending upwardly but havingv a greater degree of v bag is locatedin rear-of the vertical plane e of the body frame 'than is arranged forward of such plane. It is by reason of this structure, as will later appear, that the longi' tudinal stability of the machine is maintained during its forwardwflight.

The frame thus provided 1s supplied with 5 5 aseries Aof independent gas bags 8, prefer.

ably appropriately formed envelops extending throughout the height of the gas .bag

and disposed between the bar s'6.l Therre-E g spective envelops 8 are Wholly independent, 6 0 one from another, which envelops may, if

. desired, be dividedby transverse partitions to form a series of independent cells, though this familiar detail in a structure of thisl type is not deemed necessary of illustration.

The gas bag proper, considered as an enoutline, the bar 7 is of peculiar shape, its

inclination'from-the body frame than the inmensa tirety, is provided with a protecting covering 9, such as sheet metal or the like, overlying the frame described and following the outline thereof, as shown in' Fig. 3. `This covering acts to prevent puncture of the independent gas containers or envelops while at the same time preventing an undue distention of any one, providing, in eect, a rigid case within which are arranged the independent cells or envelops which are to be filled with buoyant gas.

An important feature of the present invention resides inthe relative dispositions of the respectivesustaining members, \\f'hich will be generally hereinafter termed gas bags, in that they are secured at their lower ends with their vertical' axes in line with the extreme outer edges of the body frame and their horizontal axes longitudinally of such frame. Furthermore, the frames of theY respectivev gas bags incline upwardly and outwardly from the body frame, or, in other words, diverge,l presenting a maximum spacing at their extreme upper ends. Brace frames 10 connect the respective gas bag frames and maintain them in the fixed relation described, tie rods 11 being provided to further insure the security of the structure.

Rotatably supported, centrally of the brace frame, including the barsfl() is a propeller shaft 12, on the upper end of which is arranged a propeller 13 of any desired form, adapted for use as a lifting propeller. This propeller is arranged between the gas bags and belowtheir extreme upper ends, operating thus at all times within ,the -rectangula-r space of which the gas bags may V b e said to form side walls. The lower end lof the propeller shaft terminates in a bevel s gear 14 slightly above the body frame, and:

rotatably supported on an auxiliary frame structure 15 secured to the body frame and base framesis a second propeller shaft 16. This shaft supports the driving propeller 1'?` and is provided on its relatively forward end with a gear 18. The gears 14 andy 18 are preferably arranged within a transmission case 19, intowhich also projects a driving shaft 20, from a motor 21, such as a gas engine or the like. The transmission mechanism includes a sleeve 22 keyed for longitudinal movement with the driving shaft 20,

the sleeve having a bevel gear 23 and a spur gear 24 adapted to engage, when adjusted,

the bevel gear 14 of the liftingpropellershaft and the spur gear 18 of the driving propeller shaft, respectively.A 3

The transmissionis controlled by a shifting lever 25 having `pin-and-slot connec- 'tion alt 26 with the sleeve, the .shaft of which lever is providedbeyond the case 19 with qangularly related arms 27, 28. Thev respective arms are connected by cables 29 i pulleys 31, mounted on the frame, and are connected, respectively, to arms 32 and 33, supported upon the yshaft 34, mounted upon the mainil frame within convenient reach of the foot of lthe driver. An operating lever 35 is connected to the shaft 34, and carries a spring-pressed catch 36, to engage one of a plurality of notches 37 in a notched segment 38 secured to the main frame. A spring 39 is connected to onel of the arms as 33, and to an. adjacent part of the main frame, the spring serving to induce action in one direction of the shaft 34, so thatl the operator may actuatethe shaft in one direction, by pressure of his foot upon the terminal of the lever 35, and permit operation in the other direction under the influence of the spring 39.

Supporting planes 40 are designed to be used in connection with the sustaining members 2, these planes being specifically constructed in any desired manner andof any preferred material, as `will adapt them for the use intended. y The planes are mounted immediately below the lower ends of the sustaining members of gas bags, and, as it is obvious, that in case of Hight, the planes will be disposed in the plane of Hight, or slightly divergent therefrom, it is clear that in this position the planes would act to re-l sist the direct elevation ofthe machine under the lifting propeller.` To avoid this air resistance, the planes must be adjustable, Y

' and for this purpose they are mounted upon a transverse shaft 41, passing through the' body frame, preferably at the upper portion thereof, the connections of the planes with the shaft being Yfixed. To permit adjustment, and to lock the planes in such adjusted position, the shaft'41 adjacent each side bar of the main frame, has secured thereon a disk 42 formed at preferred points with peripheral notches 43. Slidably supported in a bracket 44, secured to the main frame bar, is a latch 45 having a nose-end adapted for coperation -with either of the notches 43. The latch is spring-pressed in locking direction by a spring 46. The respective latches, there being one adjacent each longitudinal side bar of the main frame, are simultaneously operated through the medium of cables 47, terminally connected to the latches and extending vertically of the body frame and fixed at the lower ends to a preferred part thereof. As the drivers seat will be arranged at one side of the center'of the main frame, one of the cables 47, that is from the relatively remote latch, may be guided through suitable pulleys 48 transversely of the main frame, so that it will depend immediately adjacent the cable from the remaining latch. Both cables may be thus grasped Iby one hand and 4drawn upon tooperate the latches, such Cables, if desired, being connected into one i strand. The shaft 41 about centrally of the As illustrated in Fig. 6, I have shown` locking means permitting of but two adjustments of the planes, though it will be understood that other adjustments may be readily provided for by the use of additional notches. By withdrawing the catches and suitably pulling upon one side or the other of the cable 50, the driver may adjust the planes, in the instance illustrated, to either a vertical or horizontal position, at will, providing for the use of such planes as sustaining planes during Hight or their elimination as air resisting elements in the direct elevation of the machine.

The invention contemplates the use of a `driving propelleras a rudder and also as a peller shaft 16 is thus free for lateral swinging movement, so as to position the propeller to one side or the other of the longitudinal axis of the machine, and hence utilize this propelling force for steering purposes. To control the degree of adjustment for this purpose, the respective sides of the carriage 53 are connected through cables 56, extended over suitably guiding pulleys, to hand bars. 57 arranged on opposite sides of the driver seat, so that in the posit-ive operation of either hand bar, the propeller shaft, and therefore the propeller, will be shifted laterally' for use as a rudder.

To insure a neutral or normal driving position for the propeller, I contemplate locking the hand bars 57 when the parts are in such position. A simple means for this end is shown in Fig. 11, wherein each hand bar is provided with a fixed lug 58 adapted to be engaged by a` spring-pressed lever 59 mounted in a suitable casing 60 through which the hand bar slides. A push button operator -61 is connected to one end of the lever to permit its manual operation torelease the lock, when desired.

rEhe driving propeller is also designed to be used as a retarder and reverse driver, gaining this result through a reversal of the propeller. blades. This is accomplished at the will of the driver by means shown more y particularly in Figs. 9 and 10, whereinthe i again changethe propeller blades. '40

rear end of the propeller shaft is enlarged, or otherwise formed, to provide a vhollow extension 62. The extension is formed with diametrically opposed slots 63 through which'extends the stub shaft 641-1 carrying the blades 65. vOn the shaft 64 within the hollow `extension 62 is fixed a gear 66, and.

a rack 67 is secured within the extension to coperate with the gear. rlhe stub shaft 64' beyond the extension is rotatably mounted in brackets 68 extending forwardly fromla ring 69 which slidably engages thev extension 62. An annular operating member 70 encircles the ring 69, havingy shouldered connections at 71- therewith, a-nd being mounted for independent rotative movement therethrough. The annular operating member 70 is connected, through the medium of links 7 2, with levers 73 secured upon a shaft rotatably mounted in the carriage 53, one lever 73 being below the shaftand connected on opposite sides of the fulcrum, through the medium of cables 74;, 75, with the respective ends of a bar 76 pivotally supported within reach. of the driver, and controlled construction provides a means conveniently accessible to the driver, by which the driving propeller may be reversed, in effect, to

utilize it as a retarding element in the iight of the machine, or as a reverse drive.

Landing mechanism or the means for supporting the machine on the surface of the ground involves a wheel structure, embodying, 4in the essential details, as illustrated, a pair of forward wheels 78 and a sin le rear wheel 79, these wheels being movaly mounted in bearings carried by auxiliary framesl depending from i the main frame.` rllhe forward wheelsare mounted in. bearing blocks 8O slidable in a bearing 81 in the auxiliary frames, and cushioned against upward thrust by a spring. 82. These wheels are preferably mounted upon a single shaft y or axle 83, and the wheels al'e each provided with brake drums 84 to be engaged by the f usual brake bands '85.. The` brakes on both wheels are ysimultaneously operated through p a shaft 86 connected for actuating said brakes, and centrally provided with a fixed radial arm'87, connected to Ithe lower end of the rod 88, which projects upwardly and remesa i larged at the lower end, as at 93, to permit.

the passage of the bar 91 therethrough. ln use, the brake rod is moved downwardly until the cross rod 91 is in line with the enlarged portion of the opening 93, whereupon pressure upon the brake rod causes the bar to pass through the opening, and, at'the same time, so operate the shaft( 86 as to set 'the brakes. Release of such pressure causes the spring 90 to move the brake rod upwardly with the cross bar on the lower side of the plate 92, and thus maint-ain the brakes set. Obvious operation of the brake rod releases the brakes.

rlhe rear wheel 7 9 is designed for use as a free supporting wheel,',in order that it may readily follow the direction of travel of the machine on the surface. 'llo permit such movement, the wheel is mounted in forks 94 having an upwardly extending post 95, which, as shown in lEig. 15, is mounted for freev rotary movement in the sleeve member v96. The" sleeve `member is fixed against movement in the block 97 which is rotatably mounted, preferably in the manner shown in saidl ligure, upon one ofthe rear frame bars of the main or body frame. VThe upper end of thefsleeve member 96 is connected by a spring 98 with the body frame, the' springserving to maintain a normal position of the rear wheel, while permitting its vertical movement under strain, and on the main frame bar, the spring, of course, 'ref not only prevent puncture of said gas bags,

but to insure an absolutely uniform contour. rllhe lifting propeller operates wholly ilo between the gas bags and approximately at their point of maxlmum spread. As the gas bags are arranged below the propeller, itis obvious that the air disturbed by such propeller will be banked, in effect, and thus render more e'ective thelifting action of such propeller. Furthermore, the gas bags present their minimum dimension in the line of travel of the machine in the flying operation, and hence the air resistance incidentl to the presence of'such gas bags is reduced to a= minimum. Furthermore, it is to be noted, that assuming the center of the body nalaten frame as the longitudinal axis of the machine, a larger proportion of the gas bags 1s in rear of such axial line. This increases the buoyant tendency in the rear of the machine, and hence the driving action of the driving propeller with its tendency to disturb the longitudinal stability of the machine is overcome, and the machine completed to travel in an upright position. The divergence of the gas bags is also important, as it tends to counteract any tendency to a lateral tilting of the machine in rising. The supporting planes are to be turned to a vertical position during the direct upward movement of the machine under the influence of the lifting propeller, and are then to be turned to a horizontal position for supporting purposes during the travel of the machine, under the influence of the driving propeller. However, if, during the driving action, it is desirable to retard the machine, it is possible to secure such effect by reversing the blades of the driving propeller, or, if increased retardation is desired, by again turning the planes to the vertical position, so that they will act as brakes. The driving propeller through the means hereinbefore described, may be shifted laterally so that it will readily serve as a rudder in controlling the movement of flight.

The machine shown provides aseat support 99 on which is arranged a drivers seat 100vand a passenger seat 101. Various controls hereinbefore described are, of course, to be within convenient reach of the driver, and, if desired, in order to avoid disturbing the stability of the machine, a weight of preferred form (not shown) may be carried in the passenger seat, in the absenceA of a passenger.

The motor is here illustrated as a gas engine, and a sprocket and chain connection 102 extends from the crank shaft of such motor to a hand crank shaft 103 for cranking purposes. Fuel supply from a tank 104C is supported between the gas bags above the motor and a carbureter 105 receiving the supply by gravity through a feed pipe 106.

Through a series of cables and levers, designated generally by 107, l extend a means within reach of the driver for the control of the gas supply to the engine.

All of the details of the motor, fuel connections, and control are designed to be merely typical illustration, as any preferred details in this connection may be used.
